SERVICE INDICATOR.

' Application filed March 5, 1927. Serial I0. 172,87.

My invention relates to an improved service indicator of thetypc such as used on motor vehicles to indicate when the various lubri eating and other service operations should be performed. 7

It has for its object the provision of a service indicator in which are carried several individual rolls of comparatively narrow paper or other suitable material, on which may be kept a record of at what mileage or upon what date certain service operations should be attended to. The advantage of marking this memoranda on separate strips is that after the operation has been performed, the strips may be unrolled and the memoranda torn off, leaving a fresh space on which to write the next memoranda. In other types of service indicators, it is necessary to erase the figures or dates, and as very often happens, the operator of the vehicle may not have an eraser at that particular moment and consequently is apt to forget to keep a record of the mileage or date upon which that service operation was performed. tage of my device is that a clean space is always provided, whereas when an eraser is used, it is quite apt to leave the mcmoranda space smudgy, thereby rendering the subsequent characters illegible.

lVith the above and other objects in view, my invention will be more clearly understood by referring to the specification and accompanying drawing, in which: 7

Figure 1 is a view of the instrument board of a motor vehicle, showing my improved service indicator attached thereto.

Figure 2 is a section taken on the line 22 of Figure 1.

In the drawings, the numeral 10 indicates the instrument board of a motor vehicle upon which is usually carried the various instruments including a speedometer. Secured to the instrument board is an indicator which is held in place by bolts 12 and nuts 14. To

install the indicator it is only necessary to drill two holes in the instrument board. This indicator consists of a housing 16 and the instrument board formsthe back cover. A shaft 18 is carried by the housing. Rotatably supported on this shaft are a plurality of wooden cores 20 having wound upon them rolls 21 of comparatively narrow paper or other suitable material 22. The housing is provided with a struck down portion 24 over which the strips are drawn to provide exposed stamping inemberstlO which bear against the rolls-21. I he opposite end ofthe stamping is provided with the action of Another advanportions 26 on which may be written numbers or dates. .Baveted in thehousing is:a 28 wh1ch.1s formed with spring with a member .32 having a-bentback. port1on 34. The free ends of the strips22 are passed between themembers 32 and 34rand projected through slot 38 formed at the bend 1n the former. The portion 34 is referably so constructed that it will exert a slight pressure on the strip. This pressure together the spring members 30 serves to hold the strips firmly in position at all times and prevents the roll from becomorrnim, MICHIGAN, AssIGNoR TO A c SPARK PLUG COMPANY, or

mg unwound until desired. Ed e 40 of slot 38 is preferably sharp so that t e strips of paper may be pulled down to tear ofi' the ends, while the opposite edge 42 is offset from the edge 40 to provide a space wherein the end 44. of the strip 22 may be taken hold of by the fingers so that it may be pulled out and tornofl. Opposite the spaces 26 the housmg 18 provided with a number of words or abbreviations of words such as Oil, Axle, Trans, Bat, G. cups, Plugs, etc.

This device is intended for use in connection with a speedometer. Assuming that the owner of a motor vehicle installed this device on the instrument board at the same time he started operating the vehicle, the operat1on would be as follows. The operator would mark the number 500 in the space opposite the word Oil, the number 2000 in the space opposite Axle, the number 1000 in the space opposite Trans, a date two Weeks later than the date of starting operation in the space opposite Bat, the number 500 in the space opposite G. cups, and the number 2000 in the space opposite Plugs.

He will then occasionally compare these figures with the odometer mechanism of the speedometer and when the latter showed that 500 miles had been traveled, he would change the engine oil, and, taking hold of the end 44, would pull out the strip 22 until a clean space 26 was provided, after which he would pull the strip 22 down against the edge 40 to tear ofi' the extending end. The same would be followed in attending to the other service operations. I

The advantage of always having a clean surface upon which to write the numbers or dates is that any kind of a pencil or even ink may beused. It would obviously be diflicult to erase a mark made With indelible or 001 ored lead or ink. Even when ordinary lead is used, a smudgy appearance is left after erasing it. With my device, all that is required is to tear off the previous markings. This is much simpler and more satisfactory than erasing.

It is thought from the foregoing taken in Connection With the accompanying drawing that the construction and operation of the device Will be apparent to those skilled in the art, and that various changes in size, shape,

and proportion and details of construction may be made Without departing from the spirit and scope of the appended claim.

I claim:

A service indicating device comprising, in

combination, a housing, a shaft held in the housing to rotatably support a plurality of 20 rolls'oi material adapted to receive memoranda,the housinghaving a portion over which the material is held While receiving memoranda, a member having a slot in which the outer edge 01": the roll of material is yieldingly held, said member being provided With an edge against which the end of said material may be torn off, and a plurality of spring members serving'to exert pressure on said rolls, said spring members and the member in which said slot is formed cooperating to firmly hold said material While receiving memoranda.
